Direct Self-Acting

The KOMOTO PR-1207A pressure reducing regulators precisely control downstream pressure to predetermined set pressure. Thanks to the innovative design, they provide a quick response to sudden pressure changes. The PR-1207A series regulators offer maximum capacity, quick response, and accurate pressure control. The optimized design for fast and easy maintenance will minimize the total cost of ownership.
